question about keybinding

[Andy Spiegl]

Hi,

I'm basically using the emacs-keybinding and have my wordchars set to:
 WORDCHARS='*?_-.[]~=/&;!%^(){}<>+'

But sometimes I'd like to behave emacs-(back|fore)ward-word differently
so that it doesn't jump over dots.  Let's say when I additionally press
SHIFT together with meta-b.  I've been pondering but I can't think
of a simple way to set it up so that the WORDCHARS setting changes
depending on which key I press.

Does any of you gurus have an idea?
Thanks so much,
 Andy.

Write a widget and change WORDCHARS within it. For example, I use:

  tcsh-backward-word() {
    local WORDCHARS="${WORDCHARS:s@/@}"
    zle backward-word
  }
  zle -N tcsh-backward-word

Great!

BTW, there is no way to bind something to Meta+Shift+Backspace, no?

Thanks a lot, Oliver!

That's depends on your terminal emulator and not zsh. By using Ctrl-V
or cat -v or whatever, you can see what your terminal program sends for
a particular key. Chances are, it'll send nothing useful for
Meta-Shift-Backspace. You can use X key translation X resources to make
xterm produce your own escape sequence for a particular key combination,
though.
